Introduction Congratulations! You have just invested in a most unique wood burning stove – the Mansfield Wood Burning Stove from Hearthstone Quality Home Heating Products Inc®. The Mansfield, model 8012, is one of our largest and one of the cleanest burning, EPA certified, non-catalytic wood burning stoves. At 3.2 cubic feet firebox capacity and a low 2.8 grams per hour of particulate emissions you can be proud to join the Hearthstone family with our Premier Wood Burning Stove. The generous depth allows for straight in loading of wood up to 20 inches long!

Your purchase ensures years of clean, comfortable heat with minimal maintenance. You will receive the benefits of the most advanced technology in wood burning without the cost and maintenance requirements of a catalytic stove. The Mansfield blends modern technology with the unique beauty and heating qualities of soapstone (traditionally renowned for its even heat production and long heat retaining ability). We trust that you will appreciate the quality of our handcrafted product.

Please read this manual in its entirety. Its purpose is to familiarize you with your stove's safe installation, proper break-in, operation and maintenance. It contains information that will be useful to you now and in years to come, so keep it handy and refer to it as needed.

Use these instructions as well as national, state, and local building codes to install your stove. Be sure to maintain the designated stovepipe and stove clearances to walls, ceilings, hearth, and other combustible surfaces. This will help reduce the risk of fire. Failure to follow these instructions can result in property damage, bodily injury, and even death.

Locate your stove in a safe, convenient, open area; away from traffic flow, doors, and hallways; and near a chimney and chimney connector. Review the proper clearance measurements from combustible surfaces. You can safely reduce required clearances in most cases with a special connector pipe and special wall coverings as specified by this manual, the NFPA 211 codes, and your local authorities having jurisdiction.

Keep furniture, drapes, curtains, wood, paper, and other combustibles far away from the stove. Never install the stove in a location where gasoline, kerosene, charcoal lighter fluid or other flammable liquids are used or stored.

Locate the stove centrally in your living area to allow the heat to travel naturally to distant rooms. We

recommend that you do not locate your stove in an uninsulated basement. The amount of radiant energy required to heat concrete basement walls is so great that most of the usable heat is absorbed by them and lost.

SAFETY NOTICE: A HOUSE FIRE MAY RESULT IF THIS STOVE IS NOT INSTALLED PROPERLY. FOR YOUR SAFETY, CAREFULLY FOLLOW THE INSTALLATION DIRECTIONS. CONTACT LOCAL BUILDING OR FIRE OFFICIALS ABOUT RESTRICTIONS AND INSTALLATION INSPECTION IN YOUR AREA.

The performance of your stove depends on many variables. Since all installations are unique, the general information and operating procedures presented here can only serve as useful guidelines rather than hard and fast rules. Should you have any questions, do not hesitate to contact your dealer for additional information.

Safety Information Read and understand this Owner's Manual thoroughly before installing and using this stove.

Codes When you install your Mansfield wood stove, it is imperative that you adhere to all local codes, which can be obtained from either of the following two National sources:

American National Standards Institute, Inc. (ANSI) 1430 Broadway New York, NY 10018

National Fire Protection Association, Inc. (NFPA)

Battery March Park Quincy, MA 02269

If you are installing your Mansfield in a mobile home, follow the guidelines described in the Manufactured Home Construction and Safety Standard, Title 24 CFR, Part 3280 (United States).

Make sure to install your stove: According to the manufacturer's

recommendations.

In accordance with all applicable codes.

With the proper sized chimney.

When using your stove: Warn children and others unfamiliar with

woodstoves of the danger of touching hot, radiating surfaces of your stove. For your additional safety, obtain hearth and stove guards through your local dealer.

Follow recommended break-in procedure as outlined in this manual.

Burn natural wood only. Higher efficiencies and lower emissions result when burning air-dried, seasoned wood, as compared to green or freshly cut wood.

Use caution when loading firewood into a hot stove.

Keep the ash pan tray fully inserted and the ash door closed tightly.

Inspect the stove pipe, chimney connector and chimney, as recommended.

Ensure the removable ash lip is in place while using the stove. If the ash lip is not installed properly, the hearth may exceed safe temperatures.

Follow these safety precautions: Never modify this stove in any way, especially

the primary air control system.

Never burn kiln dried wood, painted or treated wood, solvents, trash, plywood, colored or glossy paper, artificial logs, cardboard, coal, garbage or driftwood. Especially, do not burn coal in this stove.

Never Use gasoline type fuel, kerosene, charcoal lighter fluid, or other liquid fuels or solid fire starters to start or invigorate the fire. These fuels can possibly generate carbon monoxide, which can deplete the supply of oxygen. Keep all such materials away from the stove.

Never use the stove if the ash pan door is open, damaged, not in place, or not sealing.

Never use a wood grate or other device to elevate the fire.

Do Not allow logs to rest against or otherwise come in contact with the glass when the door is closed.

Do Not slam the door or use it to force wood in to the stove.

Never over-fire your stove. (See page 21)

Never put articles of clothing or candles on a hot stove.

Do Not connect the stove to a flue that is serving another appliance. (See page 14)

Other safety guidelines Keep all combustible items such as furniture,

drapes, clothing, and other items, at least 36" (0.92 m) from the stove (See page 10)

Install a smoke detector, preferably in an area away from your wood stove.

Keep a fire extinguisher handy. We recommend the type rated "A B C."

Dispose of ashes properly. (See page 22)

Keep children and pets away from the stove; they could be burned by touching a hot stove.

Clean your chimney system as needed. (See page 18)

6

Periodic Checklist

Perform each of these tasks at the specified intervals. At the End of Every Week:

Empty ashes from the firebox and ash pan, sooner if the firebox or the ash pan begin to fill up.

At the Beginning of Every Other Month: A visual inspection of the chimney connector

and chimney for creosote is recommended depending upon the use of your stove. (Please see page 18-Creosote Formation and Need For Removal)

Check door seals using the "dollar bill test." - When the fire is out and the stove is cool, shut the door on a dollar bill. If the bill pulls out without any resistance, then your stove’s door isn't sealed properly. To tighten the seal, change the door gasket. (Refer to page 18 – Gaskets)

At the End of Every Season: Dismantle the chimney connector and clean it

thoroughly. Replace any pieces that show signs of rust or deterioration.

Inspect and, if necessary, clean your chimney.

Thoroughly clean out the inside of the stove.

Inspect all door gasket material and replace if worn, frayed, cracked or extremely hard.

Thermo-Ceramic Baffle System

To enhance the combustion efficiency and reduce the emissions of the fire in your stove Hearthstone developed an advanced THERMO-CERAMIC baffle system. This system uses a lightweight, durable ceramic material above the burner tubes to maintain the high temperatures in the secondary combustion area and maintain the low emission – high efficiency combustion you desire. This new technology will not corrode, rust dissolve or lose its strength, however it is vulnerable to puncture or cracking due to rough handling.

PLEASE EXERCISE CARE WHEN LOADING WOOD OR CLEANING YOUR STOVE, NOT TO DAMAGE THE THERMO-CERAMIC BAFFLE

Located directly above the burner tubes in the firebox, this gray sheet of material will break if wood or cleaning brushes impact it. Be careful when loading and cleaning your stove to not break this material. If this piece has been fractured or a hole is

punctured, it will cause the stove to function improperly. You must replace the board through a qualified Hearthstone dealer.

Emergency Procedures

If you have a stovepipe or chimney fire, follow these instructions:

1. Call the fire department – immediately!

2. If the fire is too threatening, leave the area and wait for the fire department. If not, perform the next three steps.

3. Close the primary air control. (see page 14)

4. Close the stovepipe damper (if present).

5. Keep the stove front, and ash doors closed!

WARNING: DO NOT ATTEMPT TO PUT OUT A STOVEPIPE OR CHIMNEY FIRE BY THROWING WATER ONTO THE STOVE, STOVEPIPE, OR CHIMNEY. THE EXTREMELY HIGH TEMPERATURE ASSOCIATED WITH SUCH FIRES CAN CAUSE INSTANTANEOUS STEAM AND SERIOUS BODILY HARM.

Once the chimney fire expires, leave the primary air control closed and let the fire in the stove die out completely. Do not fire the stove again until the stove, stovepipe, and chimney are all thoroughly inspected for any sign of damage. You must correct any damage before using your stove again.

InstallationUnpacking

Hearthstone packages your Mansfield stove with the greatest care, so that it ships safely. Under certain circumstances, however, damage can still occur during transit and handling. When you receive your stove, unpack it carefully, inspecting your stove and all parts for damage. Also, ensure that all parts are included. If any parts are damaged or missing, please contact your dealer immediately.

Installing Your Stove

First you must decide where your stove will reside. After choosing an appropriate spot, inspect this location to ensure that the stove will have enough clearance to combustible materials that would surround the stove. These combustibles can include walls, floor, ceiling, fireplace, and chimney. You must carefully consider the clearances to all of these combustibles before actually connecting your stove. When considering these clearances, also decide the kind of floor the stove will rest on. Depending on your floor, you can install your stove as it is, or use a floor protector.

Use this section to plan how to locate your stove in your particular location. Consider both the clearances of the stovepipe and the stove itself to the surrounding combustibles.

Read this chapter to obtain a sound understanding of how to properly install your stove.

If you use a close clearance connector pipe, it must be tested to UL standards and listed. Check the listing for your pipe for actual clearances. The diagrams in this manual represent typical installations, but are specific to the Simpson Dura-Vent DVL brand. Clearances cannot be reduced without the use of close clearance connector pipe and/or by protecting the surfaces per NFPA 211 standards.

Clearances to NFPA 211 Protected Surfaces You can reduce the clearances to combustible surfaces by using any National Fire Protection Agency (NFPA) approved wall protection system. Please refer to NFPA 211 for specifications and complete details. You can obtain this information directly from NFPA.

National Fire Protection Agency Batterymarch Park Quincy, MA 02269 1-800-344-3555 1-617-770-3000

Hearth Requirements & Floor Protection If the floor is wood or other combustible flooring, the stove must be placed on non-combustible floor protection that extends 16 inches to the front and 8 inches to either side of the front door opening (US).

The floor protector for the stove must have minimum dimensions of 34” x 40” (864 x 1016 mm) and must be placed as illustrated here:

Figure 3

*An example of a non-combustible floor protector would be a hearth constructed with a continuous layer of a listed backer board (such as Wonder-Board or Durock) used for ember protection with a tile, brick, slate, or another noon-combustible facing.

The chimney connector must also have floor protection under it, and extending 2 inches (50 mm) beyond each side.

Outside Air Supply An outside air source may be connected directly to this stove using the optional outside air kit (PN 90-53002). The advantage of providing outside air directly to the stove is that the air used by the stove for combustion is taken from outside of the residence rather than from within the room where

9

the stove is located. With outside air supplied directly to the stove, drafts within the room and air infiltration within the building are reduced. Use of the outside air kit may also improve stove performance in a particularly air-tight house.

The outside air kit for this stove allows for the direct connection of the stove's air intake to a minimum 3" (76 mm) diameter duct (supplied by others) which leads to the outside of the house. When considering placement of the duct from the outside of the house

to the hearth, keep in mind the need to avoid wiring and structural members in the wall.

See the following illustrations for all connection options. Choose the one most convenient. Locate the termination of the duct on the outside wall of the structure in such a manner so as to preclude the possibility of obstruction by snow, leaves or other material. Screen the opening against animals and insects (any screen, duct, clamps, and hood supplied by others).

Clearances To Combustibles

Use this section to plan the layout for your stove. Consider clearance of connector, and chimney pipe to combustibles and stove to combustibles. More specifics on installation follow.

You must follow minimum clearances for the Mansfield stove to combustibles such as walls and ceilings. You may reduce the general clearances if installing the stove near Protected Surfaces (see the following diagrams and the table on page 11).

Figure 5

Figure 6

Figure 7

Figure 8

If you use a rear heat shield to obtain reduced clearances, you must use the optional rear heat shield manufactured by Hearthstone available through your local dealer. Close clearance connector pipe must be tested to UL standards and listed. Check listings of your pipe for actual clearances. Shown are measurements typical only and specific to Simpson Dura Vent DVL brand. Clearances cannot be reduced without the use of the rear heat shield and/or with close clearance connector pipe and/or by protecting the surfaces per NFPA 211 standards

Single wall connector is 24 MSG or 25 MSG blued steel stove pipe.

Double wall connector (close clearance pipe) which must be used with a listed factory-built “Type HT" chimney and may also be used with a masonry chimney to reduce clearances, is available from several manufacturers, your dealer can help you choose. Some air insulated connector pipe models available are Simpson Dura Vent DVL and Metalbestos DS. Security, GSW and Ameritec also have acceptable close clearance connector pipe.

When used in a mobile home, a spark arrester is required.

Chimney connector shall not pass through floor or ceiling, nor any attic or roof space, closet or similar concealed space. Where passage through a wall or partition of combustible

construction is desired, the installation shall conform with NFPA 211 or CAN/CSA - B365.

It is very important to follow minimum clearances for chimney connectors to combustibles such as walls, ceilings, and when installing the stove near non-combustible surfaces. Typical chimney connector clearances are outlined below. The single wall clearances are generic, the Double wall clearances are for Simpson Dura Vent DVL.

ALWAYS CHECK THE CLEARANCE SPECIFICATIONS FROM THE MANUFACTURER OF YOUR CONNECTOR PIPE

DO NOT CONNECT THE VENT TO ANY AIR DISTRIBUTION DUCT OR AIR HANDLING SYSTEM.

Venting Components & Configuration Components of a Venting System

The complete venting system consists of several components: chimney connector, wall thimble, wall pass-through, chimney, and liner. It is absolutely necessary that you install all of these components within the clearances to combustibles discussed earlier to install your stove safely.

To protect against the possibility of a house fire, you must properly install and constantly maintain the venting system. Upon inspection, immediately replace rusted, cracked, or broken components.

The chimney connector is the stovepipe from the woodstove to the chimney. The chimney connector stovepipe must be 6" (152 mm) diameter, 24 MSG or 25 MSG blued steel connector pipe. Do not use aluminum or galvanized steel pipe - they cannot withstand the extreme temperatures of a wood fire.

A thimble is a manufactured (or site-constructed) device installed in combustible walls through which the chimney connector passes to the chimney. It keeps the walls from igniting. You must use a wall thimble when installing a chimney connector through a combustible wall to the chimney.

A wall pass-through (or chimney support package) also keeps the walls from igniting. You must use one when connecting through a wall or ceiling to a prefabricated chimney.

Only install this stove to a lined masonry chimney or an approved high temperature prefabricated residential type building heating appliance chimney. Do not connect this stove to a chimney serving another appliance; you will compromise the safe operation of both the wood stove and the connected appliance.

WARNING: DO NOT CONNECT THIS APPLIANCE TO ANY AIR DISTRIBUTION DUCT OR SYSTEM.

A liner is the UL 1777 or ULC S635 (for factory built fireplace or masonry) chimney.

You must connect your stove to a chimney comparable to those recommended in this manual. Do not use stovepipe as a chimney. Use stovepipe for freestanding installations only to connect the stove to a proper chimney.

Installing a Venting System

Stovepipe sections must be attached to the stove and to each other with the crimped end toward the stove. If creosote builds up, this allows the creosote to run into the stove and not the outside of the stovepipe and onto the stove.

Secure all joints, including attaching the stovepipe to the stove's flue collar, with three sheet metal screws. Install #10 x 1/2" (3 mm x 13 mm) sheet metal screws into the holes pre-drilled in the flue collar. Leaving off the screws can cause joints to separate from the vibration that results from a creosote chimney fire.

You can simplify connecting stovepipe by using additional accessories such as telescoping pipes, slip-connectors or clean-out tees. These accessories ease the inspection of your chimney, as well as allow you to easily dismantle the stovepipe (without moving the stove) when you periodically inspection the stovepipe connection and chimney.

Install the stove as close as practical to the chimney, while maintaining all proper clearances. Install stovepipe that is as short and as straight as possible. Horizontal runs of stovepipe should always rise away from the stove a minimum of 1/4" per foot (21mm/m).

Long runs of stovepipe to increase heat dispersal are not recommended. Using longer lengths of stovepipe or more connecting elbows than necessary increase the chances of draft resistance and the accumulation of creosote buildup.

In general, you do not need to install a stovepipe damper with the Mansfield. Some installations, however, could benefit from a stovepipe damper, such as a tall chimney which can create a higher than normal draft. In such cases, a damper can help regulate the draft. The Mansfield requires a draft between 0.06" wc and 0.1" wc. For drafts above 0.1" wc, install a stovepipe damper.

Remember, the NFPA has recommended minimum clearances for chimney connectors to combustibles such as walls and ceilings. Once the stove is installed at safe distances from these combustible surfaces, it is important to maintain these connector clearances for the remainder of the installation.

14

Connecting Your Wood Stove

You can install your Mansfield to a prefabricated metal chimney or a masonry chimney.

Connecting to a Prefabricated Metal Chimney

When connecting the Mansfield to a prefabricated metal chimney, you must follow, precisely, the manufacturer's installation instructions. Use only Type HT (2100 deg. F), prefabricated metal chimneys listed per UL 103 or ULC S629 standards.

WARNING: DO NOT CONNECT THE STOVE TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.

Ensure the size of the chimney’s flue is appropriate for the Mansfield. The Mansfield requires a 6” (152 mm) inside diameter flue for new installations. A 6” diameter flue provides adequate draft and performance. You can use an 8” (203 mm) diameter existing flue with a reducer. An oversized flue contributes to creosote accumulation. (In this case, bigger is NOT better.)

When purchasing a prefabricated chimney to install with your stove, be sure to also purchase from the same manufacturer the wall pass-through (or ceiling support package), "T" section package, fire-stops (when needed), insulation shield, roof flashing, chimney cap, and any other needed accessories. Follow the manufacturer’s instructions when installing the chimney and accessories. In addition, be sure to maintain all manufacturer’s recommendations for the proper clearances to the chimney.

There are basically two ways to install a prefabricated metal chimney:

1. An interior installation where the chimney passes inside the residence through the ceiling and roof.

2. An exterior installation where the chimney passes through the wall behind the stove then up the outside of the residence.

Whenever possible, choose an interior chimney. An interior chimney heats up more quickly and retains its heat; thus promotes a better draft and discourages the formation of creosote. An exterior chimney does not benefit from the warmth of being surrounded by the building, so it typically operates at lower flue temperatures than an interior chimney. An exterior chimney’s draft is not as strong and may experience increased creosote accumulation.

Figure 10

Figure 11

15

Figure 12

Connection to a Masonry Chimney Consider two primary elements when connecting your stove to a masonry chimney: the chimney itself and the thimble where the stovepipe connects to the chimney. Use only Code approved masonry chimneys with a flue liner. See figure 13 for instructions on installing a thimble into a masonry chimney or masonry fireplace.

Before connecting to a masonry chimney, hire a professional to examine the chimney for cracks, loose mortar, and other signs of deterioration and blockage. If the chimney needs repair, complete them before installing and using your stove. Do not install your stove until the chimney is safe for use.

Make sure the chimney’s cleanout is complete and working properly. To avoid a loss of draft, the

cleanout must close off completely. If not, the chimney will cool, your stove will perform poorly, and creosote will build up in the chimney.

Make sure the size of the chimney’s flue is appropriate for this stove and that it is not too large. Use a masonry chimney with an 8” x 8” (203 mm x 203 mm) tile size for best results. An oversized flue will contribute to the accumulation of creosote.

Minimum Requirements:

At least 3’ (0.91 m) higher than highest part of roof opening through which it passes and at least 2’ (0.61 m) higher than any part of the roof within 10’ (3 m).

Use the following checklist to ensure that your masonry chimney meets these minimum requirements:

Chimney wall construction: Brick or modular block at least 4” (102 mm)

thick. A rubble or stone wall at least 12” (305mm)

thick.

Flue liner: Minimum thickness of 5/8” (16 mm). Installed with refractory mortar. At least 1” (25 mm) air space. An equivalent flue liner must be a listed chimney

liner system meeting type HT requirements or other approved material.

Interior chimney requirements: At least 2” (51 mm) clearance to combustible

structure Fire stops must be installed at the spaces where

the chimney passes through floors and/or ceiling.

Insulation must be 2” (51 mm) from the chimney.

Exterior chimney requirements: At least 1” (25 mm) clearance to combustible

structure.

Chimney height requirements for both prefabricated metal and masonry chimneys: (See Figure 13)

At least 3 feet (0.9 m) higher than the highest part of the roof opening through which it passes.

At least 2 feet (0.6 m) higher than any part of the roof within 10 feet (3 m) measured horizontally from the top of the chimney.

This stove requires a minimum chimney height of 13 feet (4 m). The maximum allowable chimney height is 30 feet (9m).

Installing In a Mobile Home

Follow these special requirements for installing your stove in a mobile home.

Install the stove in accordance with 24 CFR, Part 3280 (HUD)

Permanently attach the stove to your mobile home’s floor. Use 3/8” holes in each leg base to bolt down the stove.

Install one of the following Dura-Vent Mobile Home Chimney & Connector Kits:

o 6DP-MH 6” Diameter S/N 9096N o 7DP-MH 7” Diameter S/N 9196N o 8DP-MH 8” Diameter S/N 9296N

Each kit includes:

Stainless spark arrester cap, storm collar, adjustable vented flashing – 0/12 – 6/12, two 24” Dura/Plus* chimney pipes, and a 24” support box with built-in starter section and trim.

* (UL or ULC approved equipment is acceptable)

CHIMNEY MUST BE REMOVED WHEN

TRANSPORTING MOBILE HOME.

WARNING: DO NOT INSTALL IN A SLEEPING ROOM

CAUTION: MAINTAIN THE STRUCTURAL INTEGRITY OF THE MOBILE HOME WALLS, FLOOR, CEILING, AND ROOF WHILE YOUR STOVE IS INSTALLED AND IN USE.

Operation Once your Mansfield is set in place, connected, and assembled, you are ready to light a fire. Hearthstone tests each wood stove before we ship, so you should be able to easily light your first fire.

WARNING: HOT WHILE IN OPERATION. KEEP CHILDREN, CLOTHING AND FURNITURE AWAY. CONTACT MAY CAUSE SKIN BURNS.

Please read this entire chapter before lighting your first fire. It explains the controls and features of your wood stove, how to choose firewood, and how to break-in your stove and use it on a daily basis.

Controls & Features

Before lighting any fires, become familiar with the location and operation of your stove's controls and features and learn how to use them. For your own safety, do not modify these features in any way.

FRONT DOOR HANDLE: A fixed handle is provided to operate the front loading door. The 10 o’clock position is open; the 7 o’clock position is closed. Pull on the door handle to make sure it is properly latched. Be sure to keep the front door closed during normal operation. Failure to do so

could allow carbon monoxide to leak into the room. Extended exposure to carbon monoxide could result in bodily injury or even death.

PRIMARY AIR CONTROL: This feature is located on the lower left side of the stove, under the removable ash lip. The primary air control allows you to regulate the amount of air entering the firebox. Generally, the more air allowed into the firebox, the faster and hotter the rate of burn; conversely, less air creates a slower burn. Push the lever to the left to open the primary air control; push the lever to the right to close the primary air control.

ASH PAN: The ash pan access door is located under the ash lip. The ash pan collects burned ash from a fire and allows you to conveniently remove the ash from your wood stove. To open the door, rotate the handle counter clock-wise. Clean the firebox of ashes as required by sliding the ash grate open, sifting the ashes across the grate into the ash pan, then returning the grate to its closed position. The ash pan is easy to remove and has a handle for convenient disposal of ashes. Once you remove the ashes, close the ash pan access door and rotate the handle clock-wise to latch.

Choosing Firewood

Burn only natural firewood (known as cordwood) in the Mansfield 8011 Woodstove. This stove is not designed to burn other fuels.

CAUTION: DO NOT USE CHEMICALS OR FLAMMABLE FLUIDS TO START THE FIRE. DO NOT USE CHARCOAL, PELLETS, COAL, ARTIFICIAL LOGS OR ANY OTHER MATERIALS AS FUEL; THEY ARE NOT SAFE. DO NOT BURN GARBAGE OR FLAMMABLE FLUIDS.

The quality of your firewood directly affects heat output, duration of burn and performance of your stove. Softwoods generally burn hotter and faster, while hardwoods burn longer and produce better coals. Density and moisture content are two critical factors to consider when purchasing wood for your stove.

The following is a list of some wood species and their relative BTU (British Thermal Unit) content. The higher the BTU content, the longer the burn. Firewood with higher BTUs is generally ideal for a wood stove.

Moisture content also plays a key role in the performance of your stove. Wood freshly cut from a living tree (green wood) contains a great deal of

20

moisture. As you might expect, green wood burns poorly. You must season green wood before using it in your wood stove. To season green wood properly, split, stack, and allow it to air dry for a period of one year. Green wood may provide less than 2000 Btu per pound, whereas dry wood can provide up to 7000 Btu per pound.

Stack the firewood on skids or blocks to keep it off the ground, cover only the top of the stack. Plastic or tarps that cover the sides of the woodpile trap moisture and prevent the wood from drying. As for stacking, an old Vermonter said, "The spaces between the logs should be large enough for a mouse to get through, but not for the cat that's chasing it."

CAUTION: DO NOT STORE FIREWOOD WITHIN THE STOVE'S SPECIFIED CLEARANCES TO COMBUSTIBLE MATERIALS.

Building A Fire

Once you understand the controls of your wood stove and have the appropriate firewood, you are ready to start a fire.

WARNING: NEVER USE GASOLINE, GASOLINE-TYPE LANTERN FUEL, KEROSENE, CHARCOAL LIGHTER FLUID, OR SIMILAR LIQUIDS TO START OR 'FRESHEN UP' A FIRE IN THIS HEATER. KEEP ALL SUCH LIQUIDS WELL AWAY FROM THE HEATER WHILE IT IS IN USE.

Breaking In Your Wood Stove

It is imperative that your stove is "broken in" slowly. Cast iron must be "seasoned"; over-firing a new stove may cause castings to crack or may damage other stove parts. Driving moisture out of the soapstone slowly minimizes the “shock” to the stone at its first exposure to high firebox temperatures. Also, curing the asbestos-free furnace cement slowly ensures adequate sealing and bonding.

The bottom layer of soapstone in your firebox is intended to prevent thermal stress and should remain in place in the firebox at all times.

When you light your first fires, the woodstove will emit some smoke and fumes. This is normal “off-gassing” of the paint used when manufacturing the woodstove. If you find it necessary, open a few windows to vent your room. The smoke and fumes will usually subside after 10 to 20 minutes of operation. The odor and smoke will end once the stove is “cured”.

The first few fires of the season may produce other odors from impurities that exist in the area

immediately surrounding the stove. Some potential impurities are cleaning solvents, paint solvents, cigarette smoke, and soot from scented candles, pet hair, dust, adhesives, a new carpet, and new textiles. These odors will dissipate over time. You can alleviate these odors by opening a few windows or otherwise creating additional ventilation around your stove. If any odor persists, contact your dealer or an authorized service technician.

Building a Break-In Fire

1) Open the door and place five or six double sheets of tightly twisted newspaper in the center of the firebox. Arrange kindling in a crisscross pattern over the newspaper. Kindling should be approximately ten pieces, 1/2" (13 mm) in diameter and 10" to 18" (254 mm to 457 mm) long.

2) Fully open the primary air control by pushing the lever to the left.

3) Light the paper under the kindling. Leave the front door slightly ajar momentarily until the kindling has started to burn and draft begins to pull.

4) Close the door and allow the fire to burn. Keep the door and ash drawer closed while the stove is in use. Make sure the ash door is in the closed position.

5) KEEP A WATCHFUL EYE ON YOUR STOVE to maintain a steady, low-heat fire. Your first fire should make the stove warm but not hot to the touch. At most, a few small chunks of wood should be added to the fire to reach safe break-in temperatures.

6) Once the stove is warm but not hot to the touch close the primary air control and allow the fire to die out completely.

7) Let the stove return to room temperature.

Your first fire and first fire each season thereafter should be built and maintained as outlined above. Your patience will be rewarded by a properly seasoned stove.

NOTE: Because of the cool flue gas temperatures present during the break-in procedure, creosote may build up quickly. Your window may also get dirty. A good hot fire will clean it.

If you adhere to the operating procedures in this manual, the steel, cast iron, stone and refractory components of your stove will give you many years of trouble-free use. With use, the color of the

21

soapstone will change and small fractures may appear on the surface. These changes do not affect the function of the stove. If a stone breaks completely, it must be replaced

Avoid the following conditions that can cause the glass, refractory panels, steel or cast iron pieces to break:

Do not throw wood into the stove. Do not use the door as a lever to force wood into

the stove. Do not load wood encrusted with ice into a

burning stove - the thermal shock can cause damage.

Do not use a manufactured log grate. Burn the fire directly on the soapstone lining the cast iron bottom of the firebox.

Normal Operation

Prior to loading the stove, ensure the ash grate, refractory soapstone, and the ash pan are in place. Ensure the ash door is closed to prevent over-firing.

Building a Fire for Everyday Use 1) Open the front door and place five or six double

sheets of tightly twisted newspaper in the center of the firebox. Arrange kindling in a crisscross configuration over the newspaper. Use approximately 10 pieces of kindling, 1/2" (13 mm) in diameter and 10" to 16" (254 mm to 406 mm) long.

2) Fully open the primary air control by pushing the lever fully to the left.

3) Light the paper under the kindling. Leave the front door slightly ajar momentarily until the kindling begins to burn and draft begins to pull.

4) Close the door and allow the fire to burn.

5) Once the kindling is burning, open the front door and add logs, small at first, to build the fire up. Ensure you keep the logs away from the glass in front in order for the air-wash system to work properly. Keep the front door and ash door closed while the stove is in use.

6) Once the fire is burning well, use the primary air control to regulate the desired rate of burn. Pushing the lever to the left opens the PRIMARY AIR CONTROL for a high rate of burn or pushing it to the right for a low rate of burn. The air control does not close completely.

Note: When opening the front door to reload or re-arrange logs, it is advisable to open the door just a

crack, pause for a moment then open the door completely. This procedure allows the firebox to clear of smoke before the door is open fully. In addition, reloading on a bed of hot, red coals reduces smoking time and brings fresh fuel up to a high temperature rapidly.

Burn Rate

HIGH BURN: 500-600 Degrees F. Fully load the firebox with wood on a bed of hot coals or on an actively flaming fire and fully open the primary air control. A high burn rate once or twice a day for 35 to 45 minutes to heat the stovepipe and chimney fully, will help minimize creosote accumulation.

MEDIUM HIGH BURN: 450-500 Degrees F. With the primary air control in the fully open position, push the control lever about ¼ of its travel to the right.

MEDIUM LOW BURN: 400-450 Degrees F. With the primary air control in the fully open position, push the lever about half to two thirds of the way to the right. A medium-low burn rate is the typical setting and is preferable if the stove is unattended.

LOW BURN: Less than 400 Degrees F. Push the primary air control inward all the way to the right. This closes the air shutter to its minimum opening. A low burn rate over extended periods is not advisable as it can promote the accumulation of creosote. Inspect the venting system frequently if using low burn rates consistently.

Over-Fire Caution

Over-firing means the stove is operating at temperatures above normal temperatures reached during High Burns outlined in the BURN RATE section. Carefully avoid over-firing, as it will damage the stove. Symptoms of chronic over-firing can include warped components, short burn times, a roaring sound in the stove or stovepipe, and discoloration of the stovepipe. A properly installed stove using fuel and following operating procedures as outlined in this manual should not over-fire.

Excessive draft, inappropriate fuel, and operator error can cause over-firing. Correct an over-fire situation as follows:

EXCESSIVE DRAFT: Contact your local dealer to have a draft reading taken. Any draft in excess of 0.1 WC requires a damper in the stovepipe. Some installations may require more than one damper.

22

INAPPROPRIATE FUEL: Do not burn coal; kiln dried lumber, wax logs or anything other than natural cordwood.

OPERATOR ERROR: Ensure all the gaskets are in good condition. Replace worn out or compressed gaskets. Do not burn the stove with the front door in the open or partially open position.

If you suspect that your stove is over-firing, discontinue use and contact your dealer immediately. Damage caused by over-firing is not covered by your warranty. Results of over-firing can include warped or burned out internal parts, cracked vermiculite panels, discolored or warped external parts, and damaged finish.

ANY SIGNS OF OVER-FIRING WILL VOID YOUR WARRANTY!

Removal & Disposal of Ashes

Remove ashes only when the stove is cold. Use a protective fireplace glove if the ash pan is warm. Exercise extreme caution when handling, storing or disposing of ashes.

The ash pan is located behind the ash door at the bottom of the stove under the ash lip. The ash pan collects burned ash from a fire and allows you to remove the ash conveniently from your woodstove. Clear the firebox of ashes, and do not let them build up too high. You can leave a thin layer of ashes in

the firebox if preferred. It is important to prevent ashes from building up around the front door opening or they will spill out, or they can pack into the gasket channel and prevent proper sealing. To remove ashes, sift the ashes across the grate into the ash pan. The ash pan is easy to remove and has a handle for convenient disposal of ashes.

Dump ashes from the ash pan directly into a metal container with a tight fitting lid. Do not place any other items or trash into the metal container. Do not pour water into the container. Replace the container’s lid and allow the ashes to cool. Never place the ash disposal container on a combustible surface or vinyl flooring, as the container could be hot!

Pending disposal, place the closed ash container on a noncombustible floor or on the ground, well away from all combustible materials, liquid fuels, or vehicles. Retain ashes in the closed container until all coals thoroughly cool.

If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all cinders have thoroughly cooled.

NEVER place ashes in wooden or plastic containers, in trashcans with other trash, or in paper or plastic bags, no matter how long the fire has been out. Coals within a bed of ashes can remain hot for several days once removed from the firebox.

23

Maintenance Monitoring Stove Temperatures

Monitor the stove temperatures with a stove thermometer (available from your dealer) placed on the top center stone of the stove. The thermometer

could read as high as 600 F (427 C) on high burn

and 300-400 F (149-240 C) on low burn.

Do not over-fire the stove. (refer to previous section).

Creosote Formation & Need for Removal

When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form creosote. These creosote vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote makes an extremely hot fire, which may damage the chimney or even destroy the house.

To prevent the buildup of creosote:

1. Burn the stove with the primary air control fully open for 30 minutes daily to burn out creosote deposits from within the stove and the venting system.

2. After reloading with wood, burn the stove with the primary air control fully open for 20 to 30 minutes. This manner of operation ensures early engagement of the secondary combustion system which, when engaged, minimizes creosote buildup in the chimney.

The stovepipe connector and chimney should be inspected at least monthly during the heating season to determine if a creosote build-up has occurred. If a creosote residue greater that 1/4" (6 mm) has accumulated, it should be removed to reduce the risk of a chimney fire.

If your glass is remaining dirty, your operating temperatures are low, therefore there is a higher risk of creosote buildup.

The venting system must be inspected at the stove connection and at the chimney top. Cooler surfaces tend to build creosote deposits quicker, so it is important to check the chimney at the top (where it is coolest) as well as from the bottom near the stove.

Accumulated creosote should be removed with a cleaning brush specifically designed for the type of chimney in use. A certified chimney sweep should

be used to perform this service. Contact your dealer for the name of a certified chimney sweep in your area (your dealer may be a certified sweep!).

It is also recommended that before each heating season the entire system be professionally inspected, cleaned and repaired, if necessary.

Gaskets

Gasket material should normally be replaced every two to three seasons, depending on stove use. If the door seal is loose, a new gasket will assure a tight seal and improved stove performance. Contact your dealer for a gasket kit, which includes instructions and gaskets for your stove.

The procedure for replacing gaskets on the glass is reviewed on page 24.

To replace door gaskets, first remove the old gaskets with a utility or putty knife. Clean all gasket channels with a wire brush. Apply gasket cement to the channels and push the new gasket into place without stretching the gasket material. The door should be shut immediately to fully press the gasket into place and assure a positive seal.

We require the use of the following gaskets:

GLASS: 60" (152 mm) Length, 3/4" (19 mm) Wide, Adhesive Backed Black Tape

DOOR: 60" (152 mm) Length, 3/8" (9 mm) Diameter, Low Density Black Tube

ASH DOOR: 32" (81 mm) Length, 1/4" (6 mm) Diameter, Low Density, Black Tube

Glass

Do not operate the stove with a broken door glass. Do not abuse the front door by striking or slamming.

When necessary, the glass can be cleaned with low alkaline content commercial stove glass cleaners, which are available from your local dealer. Never attempt to clean the glass while the fire is burning or the glass is hot. Most deposits can be cleaned by following the instructions provided with the cleaner. To clean heavier deposits, open the door and lift it straight up and off the stove with the hinge pins remaining in the door (take care to save hinge pins and washers for reuse). Lay the door face down on a work bench or table. Apply the cleaner to the glass and allow it to set for a few minutes. By laying the door flat, it will allow the cleaner to penetrate

24

rather than running off the surface of the glass. Wipe the cleaner off with a soft cloth.

Important: scratching or etching the glass will weaken the integrity of the glass. Do not use a razor blade, steel wool, or any other abrasive material to clean the glass. Use low alkaline content cleaners only.

The front door glass is a 5mm thick ceramic, shock-resistant glass, made specifically for use in woodstoves. Do not use any replacement glass other than the ceramic glass manufactured and supplied for use in this woodstove. Replacement glass is available through your local dealer.

The door glass should be replaced immediately if broken. Contact your local dealer for replacement glass, which is accompanied with instructions and everything needed for the repair. If you replace the glass yourself, wear work gloves and safety glasses.

Figure 17

The procedure for glass and glass gasket replacement is as follows:

1) Remove the door by lifting it straight up off the hinges with the hinge pins remaining in the door.

2) Place the door face down on a flat, smooth surface.

3) Apply penetrating oil to the screws in the glass retainer clips. Remove the screws to separate the glass from the door.

4) Carefully lift the damaged glass from the door and discard.

5) Peel the paper backing from the tape gasket. Apply the new gasket to the new glass as illustrated.

6) Place the gasketed glass onto the door. 7) Screw the glass retainer clips back on the door. 8) Install the door.

Stone

Occasional cleaning is all that should be necessary to maintain the natural beauty of your stove’s polished soapstone finish. Clean the soapstone with water, any non-abrasive cleaner and a soft cloth. Wipe dust from the stone with a clean cloth. Do not use chemical agents to wash the stone; do not use waxes or any polishing agents on the stone.

Care must be taken not to scratch or chip the stone. Do not set items that may scratch or chip the stone (or enamel finish) on top of your stove.

Often, with use and over time, subtle earth tones of brown, red and yellow appear on the soapstone. This is a natural reaction in the soapstone. With normal use, hair line or surface cracks may appear in the stone. Such cracks do not affect the integrity or operation of the stove and do not require replacement.

Cast Iron

Exterior cast iron parts are either painted with black, high-temperature stove paint or porcelainized with an enamel finish in various colors.

Use black, high-temperature stove paint (satin black by Stovebright®) to touch up and maintain the original appearance of painted cast iron. Use a damp sponge to wipe clean. Dry the cast iron thoroughly to prevent rusting.

Enamel castings can be cleaned with a standard glass cleaner. With time and use, a very fine, subtle network of crazed lines may appear seemingly beneath the surface of the enamel. Crazing is a natural predictable process and does not represent a flaw.

25

Troubleshooting Virtually all woodstove operators experience basic common problems at one time or another. Most are correctable and generally require only a minor adjustment of the stove, installation, or operating technique. In cases where weather conditions dramatically affect stove performance, the problems are typically temporary and solve themselves once the weather changes.

If you question whether or not your stove is producing adequate heat, the best way to troubleshoot the problem is to monitor the temperature of the stack. A 400 degree F (200 degree C) stovepipe confirms the stove is supplying sufficient heat. Keep in mind that your house itself will regulate room/house temperatures. How well the walls, floors and ceilings are insulated, the number and size of glass windows, the tightness of outside doors, and the construction or style of your house (vaulted ceilings or other open spaces which collect large percentages of heat, ceiling fans, etc.) all are determining factors of room temperature.

Your stove's performance is also dependant on its installation. One common cause of poor performance is an oversized chimney flue. Oversized chimney flues result in decreased pressure, which prevents the smoke from rising out the chimney. Oversized flues are also more difficult to heat effectively, especially when burning a high efficiency stove. Cool flue temperatures inhibit the establishment of a strong draft (and encourage the accumulation of creosote). The lack of a strong draft will cause the fire to die down and may even force the smoke to pour into the room.

If your chimney is the proper size and a strong draft is not easily established, there is the possibility of the chimney being too cold. Again, hot chimneys promote a stronger draft.

Other draft guidelines are as follows:

AN "AIRTIGHT" HOUSE: If your home is super-insulated or especially well sealed, the (infiltration) air supply to the interior of the house may be inadequate. This phenomenon of air starvation within the building can be exacerbated if exhaust fans, such as clothes dryers, bathroom fans or cook stove exhaust fans, are in operation within the home. Outfitting your stove with the optional outside air supply adaptor connected to an air duct which leads to the outside of the building should correct this problem.

TALL TREES OR BUILDINGS: These obstructions, when located in proximity to the top of the chimney can cause chronic or occasional down-drafts. When selecting a site for a new chimney, take care to consider the placement of other objects in the vicinity of the proposed chimney location.

WIND VELOCITY: Generally, the stronger and steadier a wind, the stronger (better) the draft. However, "gusty" wind conditions may cause erratic down-drafts.

BAROMETRIC PRESSURE: Chimney drafts are typically sluggish on balmy, wet or muggy days. This is a weather-related phenomenon, which generally is self-correcting as the weather changes.

BRISKNESS OF FIRE: The hotter the fire in your stove, the hotter your chimney and, therefore, the stronger the draft.

BREAKS IN THE VENTING SYSTEM: An unsealed clean-out door at the bottom of the chimney, leaky stovepipe joints, a poor stovepipe-to-thimble connection, or a leaky chimney may cause inadequate draft.

SEASONAL FACTORS: Early fall and late spring are generally difficult seasons in which to establish proper drafts. The colder the outside air (relative to room temperatures), the stronger the draft.

Operating the Stove

There are days when a draft is not easily established. As outlined above, seasonal factors or a cold chimney may be the cause. Try starting the fire by using small kindling and fuel to obtain a quick, hot fire. Tend the fire frequently with small fuel until the chimney is hot and the draft is well established.
